Cleaning the Keyboard and Mouse

IMPORTANT:
A keyboard and a mouse use USB interface. Therefore it is not necessary to power off the server when connecting
or disconnecting them.
Disconnect the keyboard from the server while the devices in the system (the server and the peripheral devices) remain
turned on. Wipe the keyboard surface with a dry cloth. Then connect the keyboard to the server.
The mouse operation depends on the degree of smoothness of the internal ball rotation. To keep the mouse ball clean,
use the mouse in a place with little dust. Follow the steps below to clean the mouse regularly:
1.
Disconnect the mouse from the USB port of the keyboard while the server remains powered on.
2.
Turn the mouse upside down, and rotate the mouse ball cover
counterclockwise to remove it. Take out the ball from the mouse.
3.
Wipe the mouse ball with a dry soft cloth.
If stains remain, use a soft cloth to wipe them off. Soak the soft cloth in
neutral detergent that is diluted with water or warm water, and squeeze it
firmly.
4.
Wipe three small rollers inside the mouse with cotton swab.
Use the cotton swab soaked with alcohol if stains remain.
5.
Put the mouse ball back into the mouse.
If the mouse or rollers are wet in steps 3 and 4, put it back after fully
dried.
6.
Place the mouse ball cover, and rotate it clockwise until it is locked.
7.
Connect the mouse to the server .
